Tiny little bug: The "leet speak" safe-word requires fonts that aren't loaded by the game, and I suspect most browsers won't have installed by default.
As a fun puzzle, I tried getting this working, and succeeded, though not necessarily in the most ideal way. The following google fonts contain the required code points:. These can be included by script, or just downloaded and included locally. AFAIK, they're all open-font licensed, so no problem:
Noto Sans Tai Viet
Noto Sans Cham
Noto Sans Tagbanwa
As reference, the following game code line got it working:
Safeword has been set to <span style="font-family: Noto Sans Tai Viet;"> ꪱׁׅ'</span><span style="font-family: Noto Sans Cham;"> ꩇׁׅ݊</span><span style="font-family: Noto Sans Tai Viet;"> ɑׁׅ֮ ℘ɑׁׅ֮tׁׅhׁׅ֮ꫀׁׅܻtׁׅꪱׁ</span><span style="font-family: Noto Sans Tagbanwa;">ׅᝯׁ</span><span style="font-family: Noto Sans Tai Viet;"> ᥣׁׅ֪ꪱׁׅtׁׅtׁׅᥣׁׅ֪ꫀׁׅܻ ϐׁׅ֒ꪱׁׅtׁ</span><span style="font-family: Noto Sans Tagbanwa;">ׅׅᝯׁhׁׅ֮</span>
Hey there!
Thank you for such a detailed comment! This is all really useful information, and I've made a note of it for future. That being said, the "Safe word" gibberish being composed of some invalid characters is intentional. I was trying to make the implication that the player has absolutely zero chance of guessing it, or even being able to input it.
Thanks again!
